Creamy Haddock, Mustard & Feta Sauce for Pasta

The first time I made this dish, I was living in a tiny seaside cottage in Cornwall. The salty air and the cries of gulls were my constant companions. I remember walking down to the harbor, the morning mist still clinging to the water, and buying the freshest haddock straight off the boats. Back in my little kitchen, with the windows open to the sea breeze, I created this creamy, comforting sauce. The combination of the flaky fish, tangy mustard, and salty feta transported me, even on the dreariest of days, back to summer holidays spent on the Greek islands. It’s a taste of the sea, sunshine, and simple pleasures.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 25 minutes
• Total Time: 40 minutes
• Servings: 4-6
• Yield: 4-6 servings
• Dietary Type: Pescatarian

Ingredients

• 500 g haddock fillets, cooked and coarsely flaked (Oak smoked prime steaks work best)
• 30 ml margarine
• 1 medium onion, sliced
• 4 garlic cloves, thinly sliced
• 15 ml flour
• 250 ml cream
• 125 ml milk
• 125 ml spring onions or 125 ml chives, chopped
• 30 ml coarse grain mustard
• 125 ml feta cheese, crumbled
• 3 ml nutmeg
• 3 ml salt
• 3 ml pepper
• 500 g desired pasta

Equipment Needed

• Large pot for cooking pasta
• Large frying pan or skillet
• Wooden spoon or spatula

Instructions

1. Begin by cooking your desired pasta according to the package instructions. Ensure you salt the pasta water generously; this is crucial for flavor. Once cooked al dente, drain the pasta, reserving about a cup of the pasta water. Keep the pasta warm until the sauce is ready. A simple trick is to return it to the pot, drizzle with a little olive oil, and cover.

2. In a large frying pan or skillet, melt the margarine over medium heat. The margarine provides the fat base for the sauce, but if you prefer, you can substitute with butter or olive oil.

3. Add the sliced onion and thinly sliced garlic to the melted margarine. Sauté the onion and garlic until they become softened and fragrant, about 5-7 minutes. Stir frequently to prevent burning. This step is vital as the caramelized flavors of the onion and garlic will form the base of the sauce.

4. Sprinkle the flour over the softened onion and garlic. Stir continuously for about 1 minute, ensuring the flour is evenly distributed. This creates a roux, which will help to thicken the sauce. Cook the flour briefly to remove the raw taste.

5. Slowly pour in the cream and the milk, mixing well with the flour mixture. It’s important to add the liquids gradually while stirring constantly to prevent lumps from forming. If lumps do appear, don’t panic! Just keep stirring vigorously; they should eventually dissolve. If necessary, you can use a whisk to smooth out the sauce.

6. Bring the sauce to a gentle boil, stirring continuously for approximately 3 minutes, or until the sauce starts to thicken. The sauce should not become overly thick; aim for a creamy consistency that will coat the pasta nicely. If the sauce becomes too thick, add a splash of the reserved pasta water to thin it out.

7. Stir in the coarse grain mustard and the crumbled feta cheese. The mustard adds a lovely tang, while the feta provides a salty, creamy element. Adjust the amount of mustard to your liking, depending on how much of a kick you prefer.

8. Gently fold in the cooked and coarsely flaked haddock. Be careful not to over-stir, as you want to maintain the flakes of haddock.

9. Add the chopped spring onions or chives, and the nutmeg. Stir gently to combine. The spring onions or chives provide a fresh, herbaceous note, while the nutmeg adds a touch of warmth and complexity.

10. Remove the frying pan from the heat. Season the sauce to taste with salt and pepper. Remember that feta is already quite salty, so taste before adding more salt.

11. Serve the creamy haddock, mustard, and feta sauce immediately over the freshly cooked pasta of your choice. Garnish with extra spring onions or chives and a sprinkle of freshly ground black pepper, if desired.

Expert Tips & Tricks

• For an extra layer of flavor, consider adding a squeeze of lemon juice to the sauce at the very end.
• If you don’t have haddock, other white fish like cod or pollock work well. You could even use smoked haddock for a more intense flavor.
• To make the sauce ahead of time, prepare it up to the point of adding the haddock. Store the sauce in the refrigerator for up to 24 hours. When ready to serve, gently reheat the sauce and then stir in the haddock.
• If you find the sauce too rich, you can substitute half of the cream with more milk or even vegetable broth.
• A splash of white wine, added after sautéing the onions and garlic, will enhance the flavor of the sauce. Allow the wine to reduce slightly before adding the cream and milk.

Serving & Storage Suggestions

Serve this dish immediately for the best flavor and texture. The creamy sauce coats the pasta beautifully when it’s freshly made. A simple green salad and some crusty bread make excellent accompaniments.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm the sauce in a saucepan over low heat, stirring occasionally. You may need to add a splash of milk or water to loosen the sauce, as it will thicken upon cooling. Microwaving is also an option, but be careful not to overheat, as the sauce can separate. Freezing is not recommended, as the sauce may become grainy upon thawing.

FAQs (Frequently Asked Questions)

A: Yes, you can substitute dried herbs. Use about 1 teaspoon of dried chives or a mix of dried parsley and dill. Add them to the sauce along with the cream and milk.

Q: Can I make this sauce dairy-free?

A: Yes, using pre-cooked smoked haddock is fine, and it will add an extra layer of smoky flavor to the dish.

Q: What type of pasta works best with this sauce?
A: While the recipe suggests tagliatelle, any pasta shape will work well. Penne, fusilli, or even a long pasta like spaghetti or linguine are all good choices. The key is to choose a shape that will hold the sauce well.
